General Fusion’s August 18, 2026 update confirms its completed July Nasdaq listing (GFUZ) and approximately US$150 million in cash, which management expects to fund planned LM26 milestones through end-2028. It reports 0.72 keV plasma heating, with 1 keV, 10 keV and Lawson-criterion goals ahead, and a first-of-a-kind plant targeted around 2035. Cash runway and plant timing are forecasts, not achieved commercialization.
